Cleaning Sensitive ITE – It’s important to get it right! Cleaning Solvent Chemistries • Alcohol-based fluids • Light hydrocarbon-based fluids • Fluorinated liquids • Chlorinated liquids Cleaning Solvent Selection Criteria • Proper cleaning solvent selection is essential to avoid ITE surface compatibility issues/catastrophic component damage. • Cleaning fluid selection/fluid type needs to be compatible with IT equipment Risks of improper cleaning/drying can lead to residues that can cause metal leaching, corrosive solder flux BEFORE AFTER

p5

Cleaning Fluid Hazards & Proposed Mitigation Cleaning Solvent Type Hazards Alcohol-based Absorb water Conductive Corrosive Volatile Flammability risk Hydrocarbon-based Relatively inert Fluorinated liquids Costly Potential environmental considerations/concerns Chlorinated solvents Toxicity concerns Environmental concerns Strict disposal regulations Demineralized water (not recommended!) No dielectric properties Evaporates slowly Leaves corrosive residues Ineffective on oil-based residues Mitigation Measures • Vendor SDS, technical & safe handling documentation should be visible and easily accessible • Assure IT hardware and equipment compatibility • Operators should wear proper personal protective equipment in line with the fluid SDS • Spill response plan and spill recovery kits should be easily accessible • Drying spaces should have ESD protection elements • Follow required facility ventilation requirements

TAN Gap: Translating Fluid Oxidation to Hardware Risk Oxidation is the initiating stressor Oxidation testing outputs like Total Acid Number (TAN) and Dielectric Dissipation Factor (DDF) may correlate to fluid & hardware longevity WHY TAN + DDF MATTER TO HARDWARE Chemical attack • Corrosion or tarnish of copper and other metals • Potential seal, coating, and polymer degradation Electrical loss • More energy dissipated as heat • Reduced dielectric margin and greater leakage-current concern • High sensitivity to polar oxidation products, ions, and contamination DDF Call to Action: Share TAN and DDF data of aged fluids with the community!

Fluid Specifications PUBLISHED TODAY BEING UPDATED Immersion Requirements Rev 2.1 • 2023 Section 4 — Foundational Document Base Specification for Immersion Fluids 2022 2026 REVISION Immersion Requirements Rev 3 WORK UNDERWAY Base Specification for Immersion Fluids BEGINS AFTER REV 3

p14

Rev 3 Highlights: Immersion Fluids 01 Updated base fluid definitions 02 Consistent temperature range for thermal properties 03 More accessible dielectric test methods • New Section 4.1 defines four fluid families: hydrocarbons, esters, fluorochemicals, blends • Hydrocarbon scope widened beyond synthetics: GTL/CTL, PAO, renewable and hydrotreated base oils • Fluorochemicals now split by sub- class: PFC, PFPE, FK, HFE, HFO • Minimum of 4 data points • Room temperature specified, ≤25 °C • High-frequency measurements achievable with widely available test methods • VNA testing with resonator cavity or coaxial probe • One test required between 20 GHz and 60 GHz; 20 / 40 / 60 GHz recommended to span PCIe Gen5/6 to 224G PAM4 1P 70 °C 2P Boiling point −10 °C Upper temperature limit
